Each CD-ROM contains a folder with all the songs in PDF format. However, renaming the folder according to the book code isn't acceptable to iGigBook, even if a *.pdf extension is added. How can I get these books into iGigBook properly?

Sorry, I should have mentioned that I'm in the Android version. Normally I do not use iTunes for anything. The PDF files (songs) on the CD-ROM are given 6-digit numbers and are not arranged in alphabetical order.

The process of creating a single PDF from those single files with the numeric names can only be done using an iOS device.

I'm trying to get help from an iOS user. I notice that the CD-ROM contains not only a folder with the songs, but also an image of the cover, another of the table of contents, and some other stuff. Does it all need to be imported to the device?

The How To that I provided a link to has all the info you need to do this. As you know iGigBook uses PDF files not image files.
